| The special processing technology of aircraft thin-wall component has always beenhampering the improvement of productivity and the using of multi-point flexible tooling makethe situation better. However, the level of development and utilization for flexible tooling arestill low. CAE technology played an important role in developing product. This paper usedCAE technology to conduct simulation and analysis for flexible tooling’s workingperformance and do some research on multi-point flexible clamped thin-wall components inmany aspects:The development level of flexible tooling technology and CAE technology domestic andoverseas were studied deeply, and the purpose and significance of this research wereillustrated clearly. Self-adaption flexible clamping technology was proposed after having aclear understanding of the forming and processing technology of aircraft thin-wall component.A flexible tooling system with3×3dot matrix was designed, which realized the flexibility ofassembling.CATIA DMU was used to carry out the kinematics simulation for the drive system of theflexible tooling and the function curves between kinematic pairs were obtained, which provedthe feasibility of the design. Hyper Works software was used to conduct finite element linearstatic analysis and model analysis for the POGO unit which at different height and thefoundation bed, some laws of deformation and vibration are obtained, and then the structuralimprovement solution was proposed; After have a deeply understanding of the way ofpositioning and clamping for thin-wall components, the vibration characteristic analysis andmachining deformation analysis of thin-wall components were carried out with ANSYSprogram, the statics and model characteristics which were under the influence of differentthickness, clamped methods, machining forces and machining positions were obtained.The whole work of this paper was summarized, and some constructive conclusions were obtained. Fi nally, the future work was discussed... |
